建立了1/2车四自由度油气悬架的T-S模糊模型。采用并行分布补偿器（PDC）结构，基于线性矩阵不等式处理方法，提出了模糊保性能控制方案，导出最优保性能控制律，针对含有参数不确定的油气悬架系统进行了仿真与实车道路试验。结果表明，与被动油气悬架相比，采用了保性能控制的油气悬架在减少振动、提高车辆行驶平顺性方面性能更优。
建立瞭1/2車四自由度油氣懸架的T-S模糊模型。採用併行分佈補償器（PDC）結構，基于線性矩陣不等式處理方法，提齣瞭模糊保性能控製方案，導齣最優保性能控製律，針對含有參數不確定的油氣懸架繫統進行瞭倣真與實車道路試驗。結果錶明，與被動油氣懸架相比，採用瞭保性能控製的油氣懸架在減少振動、提高車輛行駛平順性方麵性能更優。

A T-S fuzzy model of four Degree-of-freedom hydro-pneumatic suspension of a half-vehicle is established.Based on the parallel-distributed compensator (PDC)structure and linear matrix inequality (LMI),this paper presents a fussy guaranteed performance control scheme for the model,derives the optimal guaranteed performance control law,and completes simulation and road tests with respect to the hydro-pneumatic suspension system with uncertain parameters.The results indicate that the hydro-pneumatic suspension adopting guaranteed performance control possesses even better performance than the passive hydro-pneumatic suspension in the respect of vibration reduction and improvement of driving smoothness of the vehicle.
